Abstract
(EN)
The present invention provides a preparation method for a dye and an optical film. The method comprises: adding a rhodamine dye to thionyl chloride for reaction, and removing the thionyl chloride in a reaction solution; then adding the reactant and propenoic acid 4-hydroxy R ester to anhydrous tetrahydrofuran for reaction to obtain a second reaction solution; removing the anhydrous tetrahydrofuran in the second reaction solution; and washing the reactant with dichloromethane and methanol, and performing separation by using a chromatography column to obtain a dye monomer.
(FR)
La présente invention concerne un procédé de préparation d'un colorant et d'un film optique. Le procédé consiste à : ajouter un colorant à base de rhodamine à du chlorure de thionyle pour une réaction et à éliminer le chlorure de thionyle dans une solution de réaction ; puis à ajouter le réactif et de l'ester R 4-hydroxy d'acide propénoïque à du tétrahydrofuranne anhydre pour une réaction pour obtenir une deuxième solution de réaction ; à éliminer le tétrahydrofuranne anhydre dans la deuxième solution de réaction ; et à laver le réactif avec du dichlorométhane et du méthanol et à réaliser une séparation à l'aide d'une colonne de chromatographie pour obtenir un monomère colorant.
